A. CORPORATION OF PENNSYLVANIA VENTILATING SYSTEM Application filedNovember 6, 1919. Serial No. 336,210.

This invention relates to heating and ventilating systems andparticularly to such systems having power driven means for moving theair. The chief object of the invention is to'provide a system which willbe adaptable to the large variety of conditions met with in practice andwill be positive in action and easily controlled.

Another object of the invention is to provide the ventilating means asunits easily installed at any point and readily connected to distributethe air currents efiectively throughout the space to be ventilated.

A further object of the invention is to pro- Vide heating anddistributing means such that the system may be readily changed from aheating and ventilating means in cold weather to a cooling and aircirculating means in summer.

In the accompanying drawings, Fig. 1 is a vertical side view of aportion of a Ventilating system illustrating the invention with partsbroken away and in section.

Fig. 2 is a plan view of the same. Fig. 3 is a vertical sectional viewon line 33 of Fig. 1 and Fig. 1 is a horizontal sectional view on line&4: of Fig. 8.

In the embodiment of the invention illustrated in the drawings, supplypiping 5 carries a heating fluid to the header 6 and pipes 7 returningthe fluid through header 8 and outlet 9. This heating piping isconnected to any suitable source of heating fluid such as steam or hotwater and is enclosed in a long casing or pipe like structure 10. Air tobe heated may be supplied by air inlet 12 connected to an outside sourcethrough suitable screens and filters and provided with adjustable valvemeans 13 to regulate the supply of air. The casing or pipe 10 isextended beyond the heating pipes and at various points is provided withair distributing and ventilating units 15. Each ventilating unit 15 com-5 prises a pipe length or chamber portion 16 adapted toconnect sectionsof the supply pipe or casing 10 and these units 15 will be of standardconstruction so that installation of the system will require only thebuilding of the supply line with suitable heating means and theventilating units 15 will simply be interposed at desired points.

In the ventilating units 15 air is drawn down from the chamber or pipeportion 16 by a centrifugal fan structure 17 having oppositely directedvolute outlets 18 of a fan casing 20 fastened to the lower face of thechamber 16. The fan casing is in two parts and the lower part carries afan motor 21 tastened to the casing by flanged ring 22. The fan wheel 25driven by the motor is of the centrifugal type with spider 26 and radialblades 27 directing the air outward through discharge passages 18 anddrawing it down through the axial passage 28 from the chamber 16. c

Air is thus sucked in over heating pipes 7 and blown out in divergentstreams in desired directions at each ventilating unit. The inflow ofair is readily adjusted according to the temperature of the outside airand the number of ventilating units in operation, and when desirableheated air from the room. may be readmitted into the supply as byopening doors 30 .at the air entrance. By

varying the relative adjustments of valve means 13 and doors 30 a widerange of outside and inside air is possible from an eX- clusivelyoutside supply to an exclusively inside one.

The system of this invention is also widely adaptable in structure andeasily installed. The ventilating units may be marketed as separatestandard parts and the remainder I of the piping may be built up asdesired at the site of the installation. In warm weather when the supplyof heat will be shut off the system will still operate to ventilate andrenew the air and additional fans 35 may be added at the lowerends ofthe motor shafts to further stir the air.

While the system has been described in connection with a specificembodiment it is not intended to be confined thereto. It is obvious, forinstance, that pipes may be carried in a number of directions from asingle source as indicated at 5 and. 6 (Fig. 1) and that othermodifications may be resorted to within the scope of the appendedclaims.

I claim 1. A. ventilating unit for a heating and ventilating systemcomprising a conduit chamber adapted to form a part of a supply pipe, afan casing connected thereto, and a fan Within said casing for drawingair from said chamber and discharging it 1nto the space to be heated orventilated, said casing being in two sections, one fastened to saidchamber and the other suspended therefrom and carrying the fan and themotor therefor.

2. A ventilating system comprising a series of sections adapted to besuspended from a ceiling, heating means in certain of said sections anda plurality of separate motor driven fans in others of said sections andconduit means connecting said heating and fan sections.

3. A ventilating system comprising a series of sections adapted to besuspended from a ceiling, heating means in certain of said sections anda plurality of separate motor driven fans in others of said sections andconduit means connecting said heating and fan sections and an ad ustableair supply for said heating section.

4. An air distributing means for a ventilating system comprising aconduit section adapted to be suspended from a ceiling, a fan casingsupported from said conduit section and a fan and motor supported bysaid fan casing, the shaft of said motor being adapted to carry anauxiliary outer ventilating fan.
